HENRY D. CLEMONS, OF HARTFORD, CONNECTICUT, ASSIGNOR TO THE AMERICAN VRITING MACHINE COMPANY, OF SAME PLACE.

TYPE-WRITING MACHIN E.

SPECIFICATION forming part of Letters Patent N o. 478,223, dated July 5, 1892. Application filed April 1, 1892. Serial No. 427,315. (No model.)

To all whom t may concern:

Beit known that I, HENRY D. CLEMoNs, a citizen of the United States, and a resident of Hartford,in the county of Hartford and State of Connecticut, have invented certain new andA useful Improvements in Type-Writing Machines, of which the following,r is a specification.

My invention relates to type-writing machines provided with wide carriages, which latter, as is well known, have a considerable longer range of travel than do the carriages ot the ordinary machines. Usually the ordinary machines for use by lawers and commercial houses are provided with carriages which travel about seventy steps or spaces from right to left, while the Wide carriages, so called, employed mostly by insurance companics, have a travel generally of one hundred and twenty steps or spaces.

My invention has for its object to provide means in a wide-carriage machine for actuating the signaling mechanism, which may be set or arranged in a manner to notify the operator when approaching the end of a line.

My invention consists in the features of coustruction and combinations of devices hereinafter more fully described, and lparticularly pointed out inthe appended claims.

In the accompanying drawings, Figure 1 is a front elevation of a wide-carriage type-writing machine embodying my invention, and Fig. 2 is a perspective view of the signaling mechanism.

In both views the same part will be found designated by the same numeral of reference.

The machine illustrated is that commonly known as the Caligraph, and is more fully shown in an application filed by John M. Fairfield March 23, 1892, SerialNo. 426,078.

1 designatesthe top plate or type-ring, 2

carriage 4, of which 5 is the front rod.

6 is the rear hinge and guide-rail of the carriage, and 7 the front track or Way,'upon which run two small anti-friction rollers 8, mounted in brackets 9,'secured to the front rod et'v the carriage. The track or way is mounted on supports 10 upon the top plate, and, as usual, is provided with a scale-bar 11, preferably graduated from 0 to 120, the graduations or y divisions corresponding to the number of notches or teeth of the feed-racks, and hence the number of steps or spaces of the carriage in its movement 'from 'right to left. Upon the front rod of the paper-carriage is secured by a suitable bracket a finger or pointer 12, which depends to a position in front of thescale-bar in order to exhibit the progress of the carriage,&c. The front carriage-rod is also provided with an adjustable margin-stop 13, which is clamped to the rod by a set-screw, and which is adapted to strike against a stopll on the end of the track or way for the purposeof governing or regulating the width of margin at the left-hand side of the sheet being written upon.

On the machine frame-work is arranged a gong 15, adapted to be sounded by a hammer 16 at the lower end ofan arm 17, which at its upper end is attached to a sleeve or bearing 18, fitted loosely to swing upon a pivot-pin 19, secured to the track or way. At the left-hand end of the track or Way is secured another pivot-pin 20, upon which is mounted another I sleeve or bearing 21,'which at its under side is provided with a lug or crank 22, bearing a screw or pin 23, upon which ishooked one end of a connecting-rod 24, the opposite righthand end of which is hooked upon a similar screw or pin 25, projecting from a lug or crank 2G on the underside of the sleeve 18.

Attached to the sleeve 21 and projecting from the top of the track or way 7 is an inclined plate 27, which'is adapted to be acted upon by a trip-piece 28, pivoted in a bracket ,29, adjustable longitudinally of the front carriage-rod and secured in position by a setscrew 30. Then the carriage moves toward the left, the trip-piece by its contact with the inclined plate 27 operates to turn and rock the sleeve 21 and through the connecting-rod 24 turn and rock the sleeve 18 and raise the bell-ham mer 16. Immediately the trip-piece passes off or beyond the plate 27 the bell-hammer is permitted to drop by gravity and strike against the gong to signal the operator. In returning the carriage toward the right the trip-piece by reason of being pivoted in the bracket passes over the plate 27 without affecting the bell-hammerarm.

IOO

In view of the great length of travel of the carriage the ordinary arrangement will not suiiice if it be desired to obtain the signal at any point Within the last twenty-five degrees or divisions ont' the scale. It Will be seen that if the plate 27 were made integral with the Sleeve 1S it would not be possible to ring the bell through the trip-piece 28 after the pointer 12 has passed beyond division 95 on the scale. By my invention, however, the trippiece may be adjusted to ring the hell at the extreme limit of travel of the carriage, if desired, as well as at preceding localities.

What I claim as new, and desire to secure by Letters Patent, is

l. In a type-writing machine, the combination of a gong or bell, a pivoted belbhammer arm, an actuating-plate pivoted to a station ary part of the machine and removed from the bell-hammer arm, a connecting-rod joining the said plate and the said bell-hammer arm, and a bell-trip upon the paper-carriage.

2. In a type-Writing machine, the combinaton,\vith a gong or bell, of a be1l-hammer arm attached to a pivoted sleeve having a crank or projection, an inclined plate attached to another pivoted sleeve, also having: a crank or projection, a connecting-rod uniting said pivoted sleeves through said cranks or projections, and an adjustable bell-trip upon the papercarriage.

Signed at Hartford, in the county of Hartford and State of Connecticut, this Qlth day of March, A, D. 1802.

HENRY D. CLEMONS.
